310 Watt LED UFO High Bay | 45000 Lumens | 5000K | 277-480V

Product Overview

The 310 Watt LED UFO High Bay is designed for high-ceiling commercial and industrial environments requiring robust, high-output illumination. This fixture delivers 45,000 lumens at 5000K, supporting mounting heights typically found in large warehouses, manufacturing plants, and distribution centers. The fixture operates on 277-480V, making it suitable for facilities with higher voltage electrical systems.

With a compact UFO form factor and a 120° beam angle, this high bay is engineered to replace 1000W or 1500W metal halide fixtures. The fixture is UL and DLC Premium listed, IP65 rated for dust and water ingress, and IK10 rated for impact resistance. Standard mounting is via hook, with optional pendant or surface mount available for different ceiling structures.

Core Performance and Output

This fixture outputs 45,000 lumens at 310 watts, providing an efficacy of 145 lumens per watt. The 120° beam angle supports wide, uniform coverage in open areas. The 5000K color temperature delivers a neutral white light suitable for task visibility and safety in industrial settings.

Electrical performance includes a power factor of 0.90 and THD below 20%. The fixture supports 0-10V dimming for integration with lighting controls. At mounting heights below 20 feet, output may be excessive and require dimming or increased spacing to manage glare. At heights above 40 feet, uniformity may decrease without careful layout planning.

Adjustability and Control Options

The fixture supports 0-10V dimming for output adjustment and integration with occupancy or daylight sensors. A motion sensor accessory is available for automated control in areas with variable occupancy. Dimming range allows for tuning light levels to match operational needs or energy targets.

Beam angle is fixed at 120°, with no field-adjustable optics. Control wiring is accessible via an 8-inch dimming cord. Controls integration should be planned during installation to ensure compatibility with facility systems.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70), supporting long-term operation in demanding environments. The die-cast aluminum housing and polycarbonate lens provide durability against impact and vibration. IK10 impact rating and 4kV surge protection address common reliability concerns in industrial spaces.

Operating temperature range is -40°F to 113°F, suitable for unconditioned warehouses and manufacturing areas. The fixture is covered by a 5-year warranty.

Build Quality and Physical Characteristics

The fixture housing is die-cast aluminum with a black finish, designed for heat dissipation and corrosion resistance. The polycarbonate lens protects LEDs from dust and debris. The fixture measures 13.8 inches wide by 10.9 inches high and weighs 13 pounds.

Ingress protection is IP65, supporting installation in dusty or damp locations. The fixture includes a 5-foot power cord for flexible mounting. Hook mount is standard, with pendant and surface mount options available for different ceiling types.

Where This Product Fits Best

This 310W LED UFO High Bay is suited for large, high-ceiling environments where high-output, wide-distribution lighting is required. Typical installations include open industrial spaces, sports facilities, and large commercial buildings.

• warehouse lighting
• manufacturing facility lighting
• distribution center lighting
• aircraft hangar lighting
• basketball court lighting
• indoor sports facility lighting
• convention center lighting
• pole barn lighting

Environments with high ceilings, open floor plans, and requirements for robust, impact-resistant fixtures benefit from this design. The fixture is suitable for both conditioned and unconditioned spaces with exposure to dust, humidity, or occasional water spray.

Installation and Long-Term Use

Standard hook mounting supports rapid installation on structural beams or ceiling supports. Pendant and surface mount options are available for facilities with alternate ceiling types. The fixture?s 5-foot cord provides flexibility for connection to overhead power sources.

Routine maintenance is minimized due to the sealed, dust-resistant design and long LED lifespan. For installations with high vibration or impact risk, the IK10 rating and robust housing provide additional protection. Controls integration should be planned at installation to support dimming or sensor-based operation.

How This Fixture Is Commonly Used

Common mounting heights range from 25 to 40 feet, depending on required light levels and facility layout. Spacing typically ranges from 15 to 25 feet on center for uniform coverage in open areas. In sports or event facilities, layout may be adjusted to minimize glare and optimize vertical illumination.

Higher output allows for reduced fixture count in large spaces, but may require increased spacing or dimming to manage glare and avoid over-lighting. Layout should consider ceiling obstructions, racking, or equipment that may affect light distribution.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. It is IP65 rated for dust and water ingress and IK10 rated for impact resistance. Surge protection is rated at 4kV. The fixture is covered by a 5-year warranty.

All certifications and ratings are documented for code compliance and facility safety requirements.
